Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying AISI 4330 / 4330V open-die forgings, seamless rolled rings, bars and shafts to oil & gas drilling, downhole, wellhead and heavy-machinery projects in India and worldwide, to AISI/SAE 4330 and customer specifications.

Why AISI 4330 / 4330V for Indian drilling and downhole projects

4330/4330V is a low-alloy Ni-Cr-Mo-V high-strength, high-toughness steel with deep hardenability and an excellent strength-to-toughness balance after quench-and-temper, widely used for drilling tools and downhole components (with sour-service hardness control per NACE MR0175). For India's oil & gas and heavy-machinery sectors, 4330 suits drill collars, tool joints, jars, subs, mandrels and wellhead components.

Documented capability

Oil & gas drilling: drill collars, tool joints, jars, subs, downhole tools, mandrels.

Wellhead/completion: wellhead/completion components, high-strength mandrels (NACE MR0175 / ISO 15156).

Heavy machinery/aerospace: high-strength shafts, structural forgings.

General: bars, discs, hubs, sleeves, custom forgings.
